Directed by Noam Murro, the follow-up to the first movie – which released back in 2007 – expands on the universe, depicting events taking place before, during and after the events of 300. It welcomes back Lena Headey, Rodrigo Santoro and David Wenham, who reprise their roles from the first film and introduces Sullivan Stapleton and Eva Green in the starring roles as new hero Themistocles and villainess Artemisia.
